To all whom it may concern.'

Beit known that I, WILLIAM DOYLE, a citi- .zen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Stoves or Ranges, of which the following is a specification.

My invention relates to stoves or ranges; and it consists in the combination of devices and parts hereinafter described, and set forth Y in the claims.

The purposes of my invention are to provide in stoves or ranges and in connection with the tlues commonly employed for circulating the hot gases and with the oven airheating chambers and flues which will communicate with the flues for the passage of the gases; also, to provide means for the heating of air and conducting the same, mingling with the heated gases, to iiues around the stove and then to the exit, and also to provide means whereby heated air will be introduced into the oven, and thence have passage into the ilues leading in the fire-box; and, further, to provide specific means whereby the improvements in this invention may be employed for stoves or ranges. I attain these objects by the means illustrated in the accompanying drawings, forming part of this specication, in which# Figure l is a vertical longitudinal sectional elevation of a stove or range containing the' improvements of this invention. Fig. 2 is a horizontal section taken at line l, Fig. l. Fig. 3 is a horizontal section taken at line 2, Fig. l. Fig. 4 is a horizontal section taken at line 3 8, Fig. l. Fig. 5 is a vertical longitudinal section taken at line 4 4., Fig. 2. Fig. 6 is a transverse sectional view taken at line 5 in Fig. l. Fig 7 is a transverse sectional View taken at line 6 in Fig. 1, and Fig. 8 is atransverse sectional View taken at line 7 in Fig. l.

The same letters of reference refer to like parts throughout the several views.

In the drawings, A is the fire-boxg B, the ashspit; C, the oven; D, the horizontal top flue; D', the return horizontal iiue; D2, the front vertical iiue; DE, the lower horizontal flue. DI*l is the rear vertical flue; D5, the direct fiue, and E is the horizontal exit-flue leadingv These air-heating chambers G communicate' from their upper sides through opening g to the horizontal fines Il H, Figs. 2, 6, 7, and 8,

and these flues II communicate at their opposite ends with the vertical fines I I, which discharge into the voven C at its lower corners, as at t' t', as illustrated by Figs. l, 6, 7, and 8. J is an outlet pipe or opening from the oven to horizontal iiue D.

The airheating chambers G G have coInmunication through openings g g with horizontal air-fines K K, which communicate with the vertical sheet from air-fines K K leading to horizontal air-iiue K2 between the oven C and the flue D3, to which latter communication is had from iiue D3 through the opening 7.5. L is a horizontal sheetflue above oven C, having its lower plate provided with openings Z Z, through which air mingled with gases from the oven C can escape into said iiue L and be discharged into fire-boX A through passages L.

N, Figs. l and 2, is a horizontal damper, which, when closed, as shown by full lines, will cause the gases from the stove to pass from ilue D directly into the exit-flue E when damper N is turned open, as indicated by dotted lines in Fig. 2. N2 is a damper which controls the passage of the gases from the rear vertical ilue D-l to the eXit-fiue E. When the dampers N and N are in a closed position,as at full lines, Figs. l and 2, and damper N2 is open, as shown in Fig. 2, the passage of the gases will be from the tire-boX A through the flues D D D2 D3 D4 D5, and thereby heat the oven by the circuitous passage of the heated gases from the fire-boX to the eXit-iiue E.

The manner in which my improvements 0perate is as follows: When the register G' is open to admit air through openings b into the air-heating chambers G G and the fuel is burning in the fire-pot, with the valves N, N', and N2 turned to position to cause the gases from the burning fuel to move in the circuitous passage, as above described, one portion of the air heated in chambers G G will pass'out, after being heated within said chambers,

through openings g g into lues H H, and thence into the corner ues I I and be discharged into the oven at low points in the same, as at 'i fi, when the air mingled with the gases evolved from the cooking materials within the oven, or a portion of the s ame, will escape from the oven through passage-way .I to the iue D, while another portion of this heated air mingled with the gases in the oven may escape through openin gs Z Zinto the horizontal sheet-due L, and then have passage through the small exit-fines L' into the fire-box or the chamber containing vthe fire-box.

By my above-described improvements heated air is made to enter the oven and mingle with the gases evolved therein from the cooking material and be drawn from thence from the oven through passage-way .I into the horizontal` flue D, and be thus made to ventilate the oven by this heated air without reducing the temperature of the oven, and also lead the to the combustion of the fuel,and also cause a portion lof the heated air from the air-heating chambers G G to have passage through flues K', K', and K2 to flue D3 and contribute to the heating of the oven, and at the same time prevent the inner plates c c of the oven from having portions thereof becoming excessively heated by the heated gases movingoven, provision for admission of air to said heating-chambers, fines H H and II, communicating from said air-heating chambers to .said oven at or near its lower corners, and a passage-way from the chamber of the oven to flue D, substantially as and for the purpose set forth.

2. In a cooking stove or range, the combination, with the flue D and oven C, of aira heating chambers interposed between` the said oven and fiue, having provision for admission of air to said airlheating chambers, flue K,

'leading from said air-heating chambers to iues K', K', and flue K2, provided with opening lo, communicating with flue D3 below the said oven, substantially as and for the purpose set forth. heated air and gases from the oven through j openings Z Z into the fire-box A to contribute WILLIAM DoYLE.
